Always test that the mixer will go easily up and down
the guide bar, before the mixer has been lowered to
the desired working depth.
NOTE!
If the mixer is operated without jet ring there
must be a stop function on the guide bar
to avoid the propeller from being swung
into the wall during operation.
NOTE!
Don’t position the mixer when it is operating.
Installation in horizontal or angle position on the
guide bar
The mixer can be installed on the guide bar in hori-
zontal position or with standard angle of c:a +/-10°or
+/-20°. See Dimension drawings.
For other angle contact Flygt.
Installation alternatives for mixers
Flygt supplies equipment for a method of installation
which permits mixing over the horizontal and the verti-
cal plane.
Avoid installations where:
— there are obstacles in front of the mixer,
— the flow on the suction side of the mixer is obstruct-
ed due to the design of the tank,
— the propeller can suck down air - vortex.
To avoid vortex use a vortex protective disc or place
the mixer deeper in the liquid.
This is an absolute requirement for continuously oper-
ating mixers.
The mixer can be mounted on fixed structures, pillars,
stands, gratings, on an anchored raft etc.
When installing, keep in mind the reaction force of the
mixer, which can be up to, for: 4630 500 N
4640 900 N
4650 1800 N
4660 3000 N
4670 3900 N
4680 6600 N
NOTE!
All welded joints must be pickled and polished
before they come into contact with the liquid.
Run the cables so that they do not have any sharp
bends and are not pinched.
NOTE! The end of the cable must not be submerged.
Leads have to be above flood level, as water may
penetrate through the cable into the junction box or
the motor.
Consult your nearest Flygt representative regarding:
— choice of peripheral equipment.
— other problems in connection with installation.
In all installations, make sure that
the motor cable cannot be drawn
into the propeller.
Treat the cable as fragile, beware
that no sharp bends occure through-
out (during) installation procedure
especially by entrance flange.
Flange mounted mixer
Flange mounted mixer is an unique method for
installing mixers in tanks where guide bar or bottom
stand installation is not the optimum solution. The
mixer is assembled to a flange mounted cover by
studs, nuts and a gasket. The flange mounted cover is
calculated according to the Swedish standard TKN-87
(Tryckkärlsnorm 1987), a standard for pressurised
vessels. The flange mounted cover is made locally,
contact your nearest Flygt representative for
information.
